我正在尝试运行一个简单的 MapReduce 进程来编写 HFile，以便稍后导入 HBase 表。
提交作业时：
hbase com.pcoa.Driver /test /bulk pcoa
我收到以下异常，表明 HDFS 中不存在 netty-3.6.6.Final.jar（但它确实存在于此处）。
-rw-r--r--+ 1 mbeening flprod 1206119 Sep 18 18:25 /dedge1/hadoop/hbase-0.96.1.1-hadoop2/lib/netty-3.6.6.Final.jar
恐怕我不明白如何解决这个配置（？）错误。
任何人都可以给我任何建议吗？
这是例外：

这是我的驱动程序：
public class Driver {
public static void main(String[] args) throws Exception {
Configuration conf = new Configuration();
Job job = new Job(conf, "HBase Bulk Import");
job.setJarByClass(HBaseKVMapper.class);
job.setMapperClass(HBaseKVMapper.class);
job.setMapOutputKeyClass(ImmutableBytesWritable.class);
job.setMapOutputValueClass(KeyValue.class);
job.setInputFormatClass(TextInputFormat.class);
HTable hTable = new HTable(conf, args[2]);
HFileOutputFormat.configureIncrementalLoad(job, hTable);
FileInputFormat.addInputPath(job, new Path(args[0]));
FileOutputFormat.setOutputPath(job, new Path(args[1]));
job.waitForCompletion(true);
}
}
